Answer:
Let's represent Beryl's current age as "x".
Whitney's current age can be represented as "x - 7".
Next year, Beryl's age will be "x + 1".
And, Whitney's age will be "x - 7 + 1 = x - 6".
According to the problem statement, next year Beryl will be 1 year more than twice as old as Whitney will be:
x + 1 = 2(x - 6) + 1
Expanding the right side of the equation:
x + 1 = 2x - 11
Solving for x:
3x = 12
x = 4
So, Beryl's current age is 4 years and Whitney's current age is 4 - 7 = -3 years.
The system of linear equations can be represented as:
x + 1 = 2(x - 6) + 1 and x = 4
